The expenditure report, released on Thursday, showed Mrs Bishop continued to charter aircraft after the notorious November helicopter trip.

On March 6 this year, $4,100 was spent on a return trip to Port Macquarie, where she attended the Hastings Heroine Awards — an event recognising local women leaders.

No direct flights are available between Canberra and Port Macquarie, but the journey can take less than three hours flying via Sydney.

A six-day trip by Ms Bishop to Vietnam in March and April cost taxpayers $19,218.99, including nearly $13,000 on flights.

Justice Minister Michael Keenan spent the most on family travel at $23,350, while fellow West Australian MPs Christian Porter and Luke Simpkins were also among the highest spending in the category.
